redox-driver-sys: fix kernel GPF by acquiring IOPL before PCI I/O port access

Root cause: PciDevice::open_io_ports never called acquire_iopl(),
so the first outl to 0xCF8 triggered #GP(0) when redox-drm tried
to scan virtio-gpu PCI capabilities.

- Add ensure_iopl_acquired() helper (thread-local Once)
- Call it in PciDevice::open_io_ports before any I/O
- Add P1-pci-open-io-ports-iopl.patch to recipe
- Mirror patch to local/patches/ for durability
